THRESHING-MACHINE FEEDER.

SPECIFICATION forming part of Letters Patent No. 746,429, dated December 8, 1903.

Application filed June so. 1903.

To all whom it may concern:

Be it known that I, ISAAC S. WOOD, Jr., a citizen of the United States, and a resident of Elberfeld, in the county of Warrick and State of Indiana,have invented a new and Improved Threshing-MachineFeeder, of which the following is a full, clear, and exact description.

This invention relates to improvements in feeders for threshingmachines, the object be ing to provide a feeder of simple construction having no parts liable to get out of order and so arranged asto feed evenly from the top of the bundles.

I will describe a threshing-machine feeder embodying my invention and then point out the novel features in the appended claim.

Reference is to be had to the accompanying drawings, forming a part of this specification,

' in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional elevation of a portion of a threshing machine, showing the feeder embodying my invention; and Fig. 2 is a side elevation thereof, taken in the opposite direction.

In the drawings, 1 designates an endless conveyer arranged in the casing 2. This conveyer extends around rollers 3 4, and its upper stretch passes over an idler'5. Arranged over the inner end of the conveyer is an endless feeding-apron 6, which extends at its outer end around a roller 7 and at its inner end passes over a roller 8, the ends of the shaft of said roller 8 being extended through vertically-disposed slots 9 in the opposite side walls of the casing. By this arrangement the inner portion of the feeder is permitted avertically swinging movement, the object of which will hereinafter appear. The shafts of the rollers 7 8 are connected at the outer sides of the casing by arms 10, and from one of the extended ends of the shaft for the roller 8 a rod 11 is extended to a connection with a lever 12, mounted to swing on the outer side of the casing and having a forked lower end for engaging in an annular channel formed in the hub portion of a frictiondisk 13, mounted to slide on ashaft 14, but rotating therewith. The disk 13 engages peripherally with a friction-disk 15, on the shaft of which is a sprocket-wheel 16, having a fierial No. 163,777. (No model.)

chain engagement 17 with a double sprocketwheel-18 on the shaft of a band-cutter 19. Also extended from one set of teeth of the sprocket-wheel on the shaft of the band-cutter is a chain 20, engaging with a sprocketwheel 21 on the shaft of the roller 7,;and this roller 7 may be connected by a chain or band with a wheel on theshaft of the threshingcylinder 22. The shaft 14 has a bevel-pinion 23, which engages with a bevel-pinion 24 on the shaft of the roller 4.

In the operation it is to beunderstood that the con veyer 1 has a much slower motion than the feeding-apron 6, and the speed of motion of said conveyer is variable. As a bundle of straw is placed on the conveyer it passes underneath the band-cutter 19, where the band is severed. Then it passes to the feedingapron 6. This feeding-apronfi will be moved upward in accordance withthe thickness of the bundle and will scrape off layers from the top thereof and pass the same to the cylinder 22. As the inner end of the apron 6 moves upward it Will rock the lever 12 to move the disk 13 outward from the center of the disk 15, thus causing a very slow movement of the conveyor 1 and preventing its moving the whole bundle of straw to the threshing-cylinder. As the thickness of the bundle diminishes the inner end of the feeding-apron 6 moves downward, consequently moving the disk 13 toward the center of the disk 15, thus increasing the speed of the conveyer. At certain timesthat is, when the disk 13 is at the center of the disk 15-the conveyer will remain stationary. This only occurs, however, when an extra large bundle is placed in the machine.

With an automatic feeding mechanism embodying my invention the grain, as before stated, will be evenly fed in layers to the threshing-cylinder, and therefore there will be but very little, if any, jar to the machinery, as is the case when whole bundles are fed to the cylinder. 7

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a threshing-machine, a feed mechanism comprising. an endless conveyer, an endless feeding-apron, arranged over the inner end IOO of said conveyer, a vertically-movable roller and aswinging-leveroonnection between said 10 around which the apron passes, a shaft havrod and the first-named disk. v
